Action Star says the USB4 docking station works with Windows, macOS, ChromeOS, and Linux operating systems.

The company does not provide availability and pricing information, but considering Synaptics VMM9430 and DisplayLink DL-7400 chips will only go into production in Q4 2023, the USB4 Penta-4K120 dock should only become at that time or in Q1 2024, possibly under the BenQ brand. In the meantime, Action Star will be showcasing it at Computex 2023 next week along with other USB products that include the USB4 Triple-4K60 docking station and a USB wireless docking station with WiFi 6 and dual 4Kp60.

Why should the OS matter at all? Since DisplayLink. For anyone not familiar with this ‘technology’: it doesn’t work out of the box but you need a driver (good luck if your OS is ‘too new’ or ‘too old’) and officially only Ubuntu is supported:

Hoping and waiting for USB4 docking stations that have a 10GbE (10 Gigabit Ethernet) multi-gig koppar port built-in since there are not yet any 10GbE USB4 adapters available and 10GbE Thunderbolt adapters are still very expensive.

finally, more and more devices of this type are being presented 😉
